BACKGROUND AND PURPOSE The aim of this study was to examine the effect of transforming growth factor-beta 1, a cytokine shown to amelioriate cardiac ischemia, in a rabbit model of thromboembolic stroke. METHODS An autologous clot embolus was introduced intracranially through the right internal carotid artery in 21 New Zealand White rabbits, with seven in each group receiving either vehicle co...

Background and Purpose: The aim of this study was to examine the effect of transforming growth factor-/31, a cytokine shown to amelioriate cardiac ischemia, in a rabbit model of thromboembolic stroke. Methods: An autologous clot embolus was introduced intracranially through the right internal carotid artery in 21 New Zealand White rabbits, with seven in each group receiving either vehicle contr...

The possibility that failure of vascular resistance to increase contributes to hypotension after myocardial infarction was examined in the hindlimbs of dogs following embolization of the coronary arteries. Vascular resistance did not change significantly during sustained severe hypotension after embolization in either the intact hindlimb or in simultaneously autoperfused innervated and denervat...

1 9 1 8, there has been considerable con-troversv as to its merits in conversion of patients with chronic atrial fibrillation to normal sinus rhythm. Although actual reversion is highly successful and may be accomplished in over 80 per cent of patients ,2'3 it was felt that mural thrombi might be dislodged with resultant disastrous embolization, especially upon resumed contraction of the auricl...

A 61-year-old man presented to the emergency department with typical acute chest pain of 4 hours duration. ECG showed 2-mm ST-segment elevations in inferior leads, and the cardiac catheterization team was called for primary percutaneous coronary intervention. Angiography of the right dominant coronary artery did not show significant lesion but distal embolization and slow flow (Figure 1). Angio...

Bullet embolization after penetrating trauma is an infrequent but important phenomenon. It presents an unexpected sequelae to the otherwise predictable injury pattern of penetrating missile injury mechanism and poses a challenging diagnostic and therapeutic dilemma. Bullets from penetrating wounds can gain access to the vasculature and migrate to nearly every large vascular bed. Patients can be...

OBJECTIVE This paper seeks to evaluate the ability to deliver term pregnancies following uterine fibroid embolization, and to identify impediments to pregnancy in the embolization procedure. STUDY DESIGN Four physicians performed embolization procedures at various facilities. Patients were asked if fertility was an issue prior to embolization. We measured follicle-stimulating hormone levels b...

BACKGROUND Intraoperative cardiovascular deterioration as a result of pulmonary embolization of bone marrow fat is a potentially serious complication during vertebroplasty. The release of fatty material and thromboplastin from the bone marrow cavity during vertebroplasty may activate the coagulation cascade resulting in thrombogenesis, and pharmacological prophylaxis may therefore prevent cardi...

BACKGROUND The treatment of microcirculatory impairment will have great impact if it can be applied to myocardial infarction (MI) patients. The problem is how to study these tiny structures and microphenomenon in heart. METHODS We investigated the visualization of cardiac microvessels embolization by the mean of X-ray phase contrast imaging (XPCI), which is a recently emerged imaging techniqu...

Several studies have evaluated the efficacy of preoperative embolization in devascularizing tumors. However, no study has measured intraoperative blood loss in a single palliative surgery compared with a control group without preoperative embolization. The purpose of this retrospective study was to evaluate the efficacy of preoperative embolization on intraoperative blood loss in palliative dec...
